PowerColor Radeon HD 7850 PCS+ Testing:
Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 4.0, with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1200 using 8xAA and a five-run sequence to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card's BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will involve a 20-minute cool-down, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.
- Monitoring with MSI Afterburner
- Unigine Heaven 4.0 1920x1080 8x AA
- 5-run sequence
- 20-minute idle duration
- Temperature measured in degrees Celsius
PowerColor's dual S-shaped direct contact heat pipe-equipped cooling solution does an excellent job of keeping the GPU core cool at both stock speeds and when overclocked. The temperature difference between the stock and overclocked load temperatures are separated by a single degree. However the fan speed is pushed to 100% when overclocked. The PCS+ cooling solution shows its worth in this case with excellent noise and performance characteristics.
